ASP.Net MVC Recaptcha和严格Doctype

Question

我在我的MVC项目中使用这种this Recaptcha方法，但它不验证严格1.0 DOCTYPE。

任何人都可以帮忙吗？

谢谢

创建您自己的控件。正如你在RecaptchaControl的RenderContents方法中看到的那样，它使用一个iframe。 Iframe不符合HTML严格标准，因此您必须使用HTML对象标签。

protected override void RenderContents(HtmlTextWriter output) 
{ 
output.AddAttribute(HtmlTextWriterAttribute.Type, "text/javascript"); 
output.RenderBeginTag(HtmlTextWriterTag.Script); 
output.Indent++; 
output.WriteLine("var RecaptchaOptions = {"); 
output.Indent++; 
output.WriteLine("theme : '{0}',", this.theme ?? string.Empty); 
if (this.customThemeWidget != null) 
{ 
    output.WriteLine("custom_theme_widget : '{0}',", this.customThemeWidget); 
} 
output.WriteLine("tabindex : {0}", this.TabIndex); 
output.Indent--; 
output.WriteLine("};"); 
output.Indent--; 
output.RenderEndTag(); 
output.AddAttribute(HtmlTextWriterAttribute.Type, "text/javascript"); 
output.AddAttribute(HtmlTextWriterAttribute.Src, this.GenerateChallengeUrl(false), false); 
output.RenderBeginTag(HtmlTextWriterTag.Script); 
output.RenderEndTag(); 
output.RenderBeginTag(HtmlTextWriterTag.Noscript); 
output.Indent++; 
output.AddAttribute(HtmlTextWriterAttribute.Src, this.GenerateChallengeUrl(true), false); 
output.AddAttribute(HtmlTextWriterAttribute.Width, "500"); 
output.AddAttribute(HtmlTextWriterAttribute.Height, "300"); 
output.AddAttribute("frameborder", "0"); 
output.RenderBeginTag(HtmlTextWriterTag.Iframe); // Change this to object HTML tag 
output.RenderEndTag(); 
output.WriteBreak(); 
output.AddAttribute(HtmlTextWriterAttribute.Name, "recaptcha_challenge_field"); 
output.AddAttribute(HtmlTextWriterAttribute.Rows, "3"); 
output.AddAttribute(HtmlTextWriterAttribute.Cols, "40"); 
output.RenderBeginTag(HtmlTextWriterTag.Textarea); 
output.RenderEndTag(); 
output.AddAttribute(HtmlTextWriterAttribute.Name, "recaptcha_response_field"); 
output.AddAttribute(HtmlTextWriterAttribute.Value, "manual_challenge"); 
output.AddAttribute(HtmlTextWriterAttribute.Type, "hidden"); 
output.RenderBeginTag(HtmlTextWriterTag.Input); 
output.RenderEndTag(); 
output.Indent--; 
output.RenderEndTag(); 
}
